The answer is gas and it involves the Kinetic molecular theory which is a model used to predict gas behavior. Molecules or atoms
Answer:
i think this is right!
Explanation:
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free. The equation for the reaction is: 2K + 2H2O → 2KOH + H.
An example of a double replacement reaction is the reaction between silver nitrate and sodium chloride in water. Both silver nitrate and sodium chloride are ionic compounds. Both reactants dissolve into their ions in aqueous solution.
Answer:
H-F> H-O> O-F
while H-H is nonpolar.
Explanation:
The bond is polar when electronegativity difference of both bonded atom is greater than 0.4.
Electronegativity values of O. F and H are
O = 3.4
H = 2.2
F = 3.98
For O-F
3.98 - 3.4 = 0.58
For H-F
3.98 - 2.2 = 1.78
For H-O
3.4 - 2.2 = 1.2
For H-H
2.2 -2.2 = 0
So H-H is nonpolar.
time travel is the best option
The answer is D because it uses the electrical energy from the wall to create heat (Thermal) energy for the clothes
